Export an animation in blender with Pose helper

Hello,

Wanted to ask if there was any plan to include this function as the tool pose helper by Kijiko is pretty damn awesome.
Makes life easier and can put more constraints where needed.

So far I could only create content using his tool, and like I would like to Modify existing content with his tool, I'm kinda stuck right now as the animations I export are using the classic rig from s4s. Maybe I can try to append the control rig ?
(my understanding was that he created the tool together with you, which is why I ask here).
Maybe not the right section tho.

thanks
